' SPECIFICATION fori'ning part of Letters Patent No. maea'tldeted May 15,1894 I Applicatioii filed September 28, 1893- ieriel Nlildtlfit'lOOi (Ho medal.) I V A may concern: Be it known that I, ()SSIAN C. DAVIS, a citizenbf the United States, residing at Racine,

in ther'county of Racine and Stateof Wiscon SID, have invented certain new and useful Improvements in Boilers; and I'do hereby declare the following to be a full, clear, and exact description of the, invention, such as will enable others skilled in the art to which t appertains to make and use the same- My present invention isan improvement in boilers, that is, water heaters or steam generators and it consists of certain improved constructions and combinations of partswhereby water is more readily heated or steam more quickly generated.

The best form in which I have contemplated embodying myinvention is illustratedin the accompanying drawings and the said invention is disclosed in the following description and claims. p '1 In the drawings, Figure l is a vertical section of my improved boiler, and Fig. 2 is a partial top view of the same. I

In the figuresA is the outer shell of the boiler B is the inner shell forming the fire box.. The shells A B are united at the base and at the upper ends the shell A is provided with a head a, and the shell B with a head b. These heads are a distance apart andthey are connected by tubes b"for the passage of the products of'combustion through theboiler The headb of shell B is provided with a downwardly extending inner ordepending shell (3' 1 pending portion 0 of the boiler. A space must which increasesin size as it descends and is provided at its lower end with a re-entrant bottom c'forming the toplor dome of the fire box. Within this depending part of the boiler or heater is placed the inverted funnel shaped deflector D. This deflector is preferably supported upon the bottom c of the de- -be provided between the lower edge of the deflector and the bottom to perm it the free passage of the water between them; and'in order .to secure this I provide the lower edge of the deflector with feet cl which rest upon the bottom 0. The upper tubular end of the deflector is-loosely held in the outlet through the head a. In this instance the head is provided with a socket E to which a pipe may be secured to conduct away the out-going stream deflector Dis provided with projeetions e e to form a space between-the deflector and the socket."-.

grate and the top of easing A is fitted with a I hood for. conducting the. products of combustion to a stack or u'p-take of usual construction; I i

t' The spacebetween the shells A, B,the'heads stitute the interior of the boiler and the shell fA is provided with one'or more inlets at the walls of. the fire box. The water then passes, upward and through the series of pipes 15''. where it is further heated, then downward beneath the deflector and is brought into contact with the crown or dome of the fire box and is highly heated, expanding and rising fiector and passiug in a\strongcurrent out through the outlet pipe. In case any steam isgenerated in the boiler it passesout through the upper end of the same andthe outlet opening. Theconstruction also gives excellent results as a steam generator for heating and other purposes. In such case the deflector lines shown in the drawings.

bottom a of the boiler has a considerable degree ,of heat imparted to it and the water bequickly raised to a high degree of temperature, while the inclineof the deflector concentrates the same into the tubular portion giving the sharp action before described.

'\ What Iclaim,'and desire to secure byLetters Patent, is+- 1.. A water boiler having a bottom portion 'a, b and within the dependin g portion C) con-,

ture of the same andthus greatly protecting the deflector or fthrough the space between tween itand the bottom is by 'reason of this,

' oijwater or steam, andrthe upper end oli the 4 In practice the fire boi'is provided with a within the depending portion 0 when it passes quickly through the tubular part of the de tube may if desired be cutolf atth e dotted The lower partdeilector C resting upon the forming lire top of the lire box and provided wiih-zw. in verte funnel shaped deflector restmg; on and R pported byihe said bottonipor- Lien snbstanl ly as described.

2. A water heater or boiler having a reentrout botem and provided with an inverted funnel engined deflector resting on'and supper-led by said bottom, substantially as described. Y

8. The combination with a. water heater or boiler, of an infvorted funnel shaped deflector and provision for the escape of steam between ille top of said deflector and boiler, Substantially as described. 1

4. The combination with water heater or boiler provided with outlet and inlet. of an inverted funnelsliaped deflector adjacent to the outlet, resting on and supported by the bottom of the boiler of tubular pessagee for the prodnot of combustion passing through the boiler between the inlet and sand deflector, substantially as described.

5. The combination with a water heater or boiler, provided with an outlet and inlet, of 23, depending portion extending to near the bottom of the boiler having an interior passage presence oftwo'witnesses. v
